Time to say good bye… My HP StorageWorks EVA 5000 was a big challenge. A few years ago I started this project with one HSV110 controller. Step by step I created my own EVA 5000 with parts that I bought everywhere in the world. 😉 Since two years this system is running in my home […]
A little reminder for me. 😉 Since Oracle Solaris 11 Express you can set the zil_disable tunable with the zfs set sync option. Disable ZIL: # zfs set sync=disabled demopool/test Enable ZIL: # zfs set sync=always demopool/test
Yesterday I received the news that Oracle plans to port their own Linux, Oracle Enterprise Linux, to SPARC. A pretty cool idea. 🙂 But after talking with a very good friend I’m not sure if this news is a good news. Why pay lot’s of money for porting a operating system to a new platform? […]

Today my hard disk hot-swap trays arrived. 🙂 Yippiieee… time to complete my storage server. The new hot-swap trays had no labels, so I created them myself. It looks pretty nice! Next step is getting some more disks and a suitable rackmount-kit. My private datacenter grows and grows. 🙂
Sunday morning I read an interesting article about a VMware installation based on HP BladeSystem with Virtual Connect Flex-10 modules. The article contained lots of screenshots and I saw serveral changes within Virtual Connect Manager. So I decided to upgrade the firmware of my entire HP BladeSystem including the blade servers and interconnect modules. The update […]
At work we decided to implement Nagios as a monitoring tool. A colleague started to install and configure Nagios Core and some add-ons. But I was not really happy with it. Nagios Core is very uncomfortable and complicated and the add-ons are not mature enough for productive usage. That’s why I decided to search for […]
